Just got my Vios 2023 in November. I think it is the same for both E and G specs, G specs only gains the front windows acoustic glass.

However, do not expect much in cabin quietness as it is only on par with other B segment rivals. I can still hear a lot of road, cars and wind noise coming from the doors especially at the rear. Squeaking sound is very prominent when going on bumpy roads which I plan to file a complaint during my 1000 km service this week.

Just checked, you are right it is also available on the E variant too!

But to be honest, I find cabin quietness isn't as great on the latest vios. Less road noise from the bottom but lots of noise from passing vehicle and from the wind...

I also have a city hatchback in the family and I find it has better door insulation than the vios, but the road noise loses out to vios. I guess its due to the fact the City's toyo tires may not be as good as the conti premium contact on the vios.
